  • Abstract:
  • Eprosartan mesylate (EM) is an angiotensin receptor blocker (ARB) used to treat hypertension. It has an oral bioavailability of 13%. The work intends to evolve eprosartan mesylate of solid lipid nanoparticles (EM-SLNs) to enhance bioavailability. EM-SLNs were developed using hot homogenization followed by ultrasonication by using lipids dynasan 118, dynasan 116, and dynasan 114. The optimized formulation EM-SLNs (F7) showed the particle size is 151.3 nm, poly disperse index (PDI) shows 0.210 and zeta potential (ZP) values were -31.74mV, which indicated the stability of developed EM-SLNs. The entrapment efficiency (EE) was found to be 85.10%. EM-SLNs were established as likely spherical with a lustrous exterior, as making do with scanning electron microscope (SEM). Relative bioavailability of the optimized EM-SLNs (F7) was increased by 1.84 times, differentiated with the coarse suspension of pure drug.
